抚顺矿区煤层气开发的几点认识

Several Knowledges on Exploitation of Coal Bed Gas in Fushun Mining Area

通过对抚顺煤田煤层气赋存条件的研究,认为抚顺煤田存在封闭性良好的构造条件,有利于煤层气保存的巨厚盖层,较厚的煤层与适中的煤变质程度,以及有利于煤层气开发的较高含气量与较大的煤层渗透率。在考虑抚顺矿区是老矿区的具体情况下,对地面钻井开采煤层气的布井与施工提出了几点认识。

Through research on preservative conditions of coal bed gas in Fushun coalfield, consider that in the Fushun coalfield, there are structural conditions on good confining nature, and huge thick covering strata favourable to preservation of coal bed gas, and thicker coal-bed and moderate coal metamorphic grade, and higher gas content and permeability of coal-bed which favourable to exploitation of coal bed gas. Based on Fushun mining area belongs to old mining area, submitted several knowledges on mining of coal bed gas with surface drill well.
